What is surface plasmon resonance?
Surface plasmon resonance (SPR) is a technique used to measure the binding interactions between molecules in real-time without the need for labels.
What are the applications of SPR?
SPR is used in drug development, antibody characterization, and studying protein-ligand interactions.
How does SPR determine binding affinities?
SPR measures changes in refractive index near a sensor surface, allowing for the calculation of kinetic constants and binding affinities.
What types of interactions can be studied with SPR?
SPR can study various interactions, including protein-protein, protein-DNA, and protein-glycan interactions.
Is SPR a label-free technique?
Yes, SPR is a label-free technique, meaning it does not require fluorescent or radioactive labels to detect binding events.
